[Polyual Construction Proposal] Sulfur Countermeasures for Hot Spring Areas

[Polyual Construction Proposal] Sulfur Countermeasures for Hot Spring Areas

Proposal for the installation of polyurethanes to prevent deterioration of outdoor units caused by gases containing sulfur!

"Polyual" is a corrosion prevention paint for aluminum fins patented by Blygold. Deterioration of outdoor units caused by gases containing sulfur, such as sulfur dioxide, can lead to refrigerant leakage, and in extreme cases, the outdoor unit may suddenly become unusable within about two years, making it one of the most challenging issues for air conditioning units. By applying this product, a coating film is formed on the surface of the aluminum fins, helping to prevent deterioration. 【Features】 ■ Suppresses the growth of bacteria and mold on aluminum fins of heat exchangers ■ Addresses heat exchangers that cannot be protected even with cationic coatings ■ Protects outdoor units in salt damage areas where salt damage occurs even with salt-resistant specifications ■ Provides semi-permanent protection for fins through touch-up repairs ■ Maintains heat exchange performance with a thick coating and high thermal conductivity, etc. *For more details, please refer to the PDF document or feel free to contact us.

Q&A page regarding the aluminum fin deterioration prevention paint "Polyual."

Introducing answers to questions regarding the application of aluminum fin deterioration prevention paint!

"Polyual" is a corrosion prevention paint for aluminum fins patented by Blygold. By applying this product, a coating film is formed on the surface of the aluminum fins, helping to prevent deterioration. We have answered questions regarding this product, and here are some examples. 【Q&A Examples (Excerpt)】 ■ Can it be applied to home-use, small air conditioners? ■ Where can I buy Polyual? ■ Can it be applied to new units as well? ■ Will it increase electricity consumption? ■ Can the air conditioner be used during application? And more. *For more details, please refer to the external link or feel free to contact us.

Comparison with stainless steel fins and copper fins

Comparison with stainless steel fins and copper fins

Comparing "stainless steel fins," "copper fins," and "polyural"! Detailed explanation provided.

Stainless steel fins deteriorate under severe salt damage conditions, and their low thermal conductivity is well known. Copper fins excel in thermal conductivity due to their close contact with copper tubes, but they are expensive, and the salt resistance of copper is not much different from that of aluminum, resulting in a deterioration rate that is said to be about half that of standard aluminum fins (deterioration between dissimilar metals can be avoided). Under conditions where standard aluminum fins deteriorate in three years, copper fins will deteriorate in about five to six years. Therefore, we propose our aluminum fin deterioration prevention coating, "Polyual." 【Features of Polyual】 ■ Provides semi-permanent protection ■ Maintains and restores the initial performance of fins ■ Effectively protects the air conditioning unit from salt damage and polluted gases ■ Protects thoroughly from the inside of the fins to the ends ■ Shuts out the intrusion of salt damage and pollution *For more details, please refer to the PDF document or feel free to contact us.

Can it be overcoated with cation?

Can it be overcoated with cation?

A detailed explanation of whether topcoating can be done on cationic electrodeposition coating!

We often receive inquiries about whether it is possible to apply a topcoat over cationic electrodeposition paint. The answer is yes, and there are successful cases. However, when a topcoat is applied over cationic paint, the adhesion is dominated by the cationic layer, which is prone to cracking. If the cationic coating cracks or peels, the topcoat may also tear, and in this case, it will not be covered by warranty. Using a thin pre-coat film with salt damage resistance reduces the risk, but the adhesion will still be weaker compared to painting directly on aluminum or copper. Considering the costs, we recommend painting directly on aluminum or copper. *For more details, please refer to the PDF materials or feel free to contact us.*

Comparison with cationic electrodeposition

Comparison with cationic electrodeposition

Comparing "cationic electrodeposition" and "polyurethane"! A detailed explanation will follow.

Cationic electrodeposition is an excellent rust prevention technology; however, in the case of heat exchangers, a film thickness of 20 microns, which is expected to provide sufficient rust prevention, can affect thermal efficiency, leading to an increase in electrical material quantity and potentially requiring larger equipment. Therefore, we propose our aluminum fin deterioration prevention coating, "Polyual." 【Comparison】 <Cationic Electrodeposition / Polyual> ■ Application: At manufacturing / At manufacturing, installation site - Since thinner is used for Polyual application, if installed indoors, painting must be done outdoors before installation. ■ Film thickness: 8–30 microns / 20–25 microns ■ Thermal conductivity: Low / High - Polyual has thermal conductivity equivalent to aluminum. ■ Repairability: Not possible / Possible *For more details, please refer to the PDF document or feel free to contact us.

Comparison with precoat

Comparison with precoat

Comparing "Precoat" and "Polyural"! Detailed explanation to follow.

The outdoor units designed for salt damage resistance and heavy salt damage resistance use aluminum fins that are pre-coated with a polymer, which protects the aluminum from salt damage and other hazards. However, while the thickness of the Polyual membrane is 20 to 25 micrometers, the pre-coat is only about 2 to 3 micrometers thick. After being exposed to salt damage for 3 to 5 years, rust may occur, or the pre-coat membrane may degrade due to ultraviolet rays. Additionally, since the pre-coat involves processing aluminum sheets coated with polymer, the cut surfaces, internal cutouts, and contact points with copper pipes are exposed to the outside air, making them entry points for salt damage and corrosion. The aluminum fin deterioration prevention coating "Polyual" addresses these issues. [Overview] The Polyual coating membrane is applied after the heat exchanger assembly, ensuring that both the contact points with the copper pipes at the fin tips and the internal cutout areas are well protected. In the salt damage specification pre-coat, these areas are exposed to outside air. *For more details, please refer to the PDF materials or feel free to contact us.
